+@deftypefun {char *} basename (const char *@var{filename})
+The GNU version of the @code{basename} function returns the last
+component of the path in @var{filename}.  This function is the prefered
+usage, since it does not modify the argument, @var{filename}, and
+respects trailing slashes.  The prototype for @code{basename} can be
+found in @file{string.h}.  Note, this function is overriden by the XPG
+version, if @file{libgen.h} is included.
+
+Example of using GNU @code{basename}:
+
+@smallexample
+#include <string.h>
+
+int
+main (int argc, char *argv[])
+@{
+  char *prog = basename (argv[0]);

+@comment XPG
+@deftypefun {char *} basename (char *@var{path})
+This is the standard XPG defined @code{basename}. It is similar in
+spirit to the GNU version, but may modify the @var{path} by removing
+trailing '/' characters.  If the @var{path} is made up entirely of '/'
+characters, then "/" will be returned.  Also, if @var{path} is
+@code{NULL} or an empty string, then "." is returned.  The prototype for
+the XPG version can be found in @file{string.h}.
+
+Example of using XPG @code{basename}:
+
+@smallexample
+#include <libgen.h>
+
+int
+main (int argc, char *argv[])
+@{
+  char *prog;
+  char *path = strdupa (argv[0]);
